LOCK HAVEN, Pa. (AP) -- Officials have identified three men killed when a small plane chartered by the Forest Service crashed in north-central Pennsylvania.

The U.S. Department of Agriculture on Tuesday said two Forest Service employees from West Virginia died in the crash in Lock Haven, about 150 miles northwest of Philadelphia.

The Forest Service says 29-year-old Dan Snider of Pentrees, W.Va., and 46-year-old Rodney Whiteman of Morgantown, W.Va., worked for the Forest Health Program of the Northeastern Area and were conducting an aerial pest detection survey.

Clinton County Coroner Donald Walker identified the pilot as Patrick Jessup, of New York state.

The Federal Aviation Administration says the plane went down Monday as it approached William Piper Memorial Airport. The plane struck a house and ended up in the street. No injuries were reported on the ground.
